Filed: 1985-03-26
Abstract: PURPOSE:To attain observation with a current-differential quantum efficiency curve showing a mode change by constituting the bias power source of a semiconductor laser to be measured with an iteration sweep signal generator and a fine amplitude sine wave generator. CONSTITUTION:When a bias current available from superimposing the saw-tooth signal of the generator 2 upon the sine wave signal of the generator 5 is applied to the semiconductor laser to be measured 1, the optical signal turns out to be a signal obtained by superimposing the sine wave signal upon the saw-tooth signal. Here, when the output voltage of a resistance 8 and that of a resistance 11 are applied to the horizontal axis and vertical one of a cathode ray oscilloscope 15, a current-output characteristic as shown by the solid line in figure can be obtained. On the other hand, the sine wave signal being the output voltage of a resistance 13 is inputted through an amplifier 14, thereby obtaining the current-differential quantum efficiency as shown by the broken line in the figure. It emphasizes an inflection point, and accordingly a mode changing point can be easily observed.

Title: Pattern forming method of transparent conducting film
Inventor: NAGATA MITSUO
IPC: G02F1/1333
Filed: 1978-05-23
Abstract: PURPOSE: To form the conducting film of a minute pattern with a high yield in the case of the matrix liquid crystal display or the like by applying the photo etching after forming the metal film on the conducting film when the transparent conducting film is formed in stripes.  
     CONSTITUTION: The transparent conducting film (nesa film) 6 is formed on glass substrate 5; metal thin film 7 is formed on film 6 by the vacuum evaporation or the like; and photo resist 8 is formed on film 7. The pattern of stripe-shaped photo mask 9 is transferred to the resist layer, and then the metal thin film and the nesa film are etched away in sequence with the resist layer used as the mask. Then the remaining resist layer and the metal thin film are exfoliated finally to form the nesa film in a desired pattern. In this case, ultraviolet rays 10-1W10-3 which give sensitization to the mask's transparent part through the resist are reflected by the metal thin film. As a result, no sensitization is given to the resist under the dark area of the mask by reflection on the lower surface of the glass substrate given through the nesa film, accordingly securing a high-yield pattern formation even with a minute pattern space.

Title: Composite heater
Inventor: ABE YUKIO
IPC: F24C7/02
Filed: 1987-03-17
Abstract: PURPOSE:To provide a low cost composite heater which has a high level of thermal efficiency and safety without requiring a divider plate or heat insulating material by stopping a cooling fan at the time of the simultaneous heating and the oven heating, and switching the output level of microwave generator to a low level at the time of the simultaneous heating. CONSTITUTION:Because a cooling fan 7 is stopped at the time of the oven heating and the simultaneous heating, the heat dissipation is substantially reduced. As a result, not only the thermal efficiency is improved, but also the uniformity of heat distribution in the heating chamber is not impaired. Further, because there is not too great a difference in the temperature distribution in the equipment compartment containing the microwave generator 6 from that of the oven heating mode, the layout design of components becomes easier, shortening the design time requirement. Moreover, because the anode terminal temperature of the microwave generator can be reduced as low as that which does not adversely affect the practical use by switching the output of the microwave generator 6 to a low level at the time of the simultaneous heating, the life of the microwave generator is not impaired, and a low cost composite heater which has a high level of thermal efficiency and safety can be provided without requiring a divider plate or heat insulating material.

Filed: 1989-03-14
Abstract: PURPOSE:To effectively attain a diagnostic operation with high accuracy by deciding a real abnormality factor when the lower limit probability of a certain abnormality factor is higher than the upper limit probability of another abnormality factor. CONSTITUTION:The upper limit probabilities are obtained for all abnormality factors, and the abnormality factor (maximum abnormality factor) having the maximum upper limit probability is obtained. Then the overall probability is obtained together with the lower limit probability of the maximum abnormality factor. Finally the maximum abnormality factor is decided as the real abnormality factor when the lower limit probability of the maximum abnormality factor is higher than those of other abnormality factors. Thus it is possible to perform the diagnostic operation with high accuracy with the use of the calculation value that is required for the acquisition of the overall probability and the lower limit probability of the maximum abnormality factor.
